ObjectiveTo explore the current situation and influencing factors of humanistic care experience among patients visiting traditional Chinese medicine （TCM） outpatient clinics in China， and to provide a basis for optimizing TCM-characterized services in both TCM and Western medicine hospitals. MethodsA multi-center cross-sectional study was conducted using convenience sampling to select 35 hospitals across 13 provinces in China （including 3 TCM hospitals and 32 TCM outpatient clinics in general hospitals）. A total of 3，430 patients were surveyed using the general information questionnaire and the Outpatient Humanistic Care Experience Questionnaire， with data collected via Questionnaire Star. Univariate analysis and multiple linear regression were employed to examine the impacts of patient characteristics， visit characteristics， hospital type （TCM hospital/general hospital）， and geographic region （eastern/central/western） on humanistic care experience. ResultsThe total score of humanistic care experience was 194 （188， 233）. Univariate analysis showed that gender， educational level， current residence， per capita monthly household income， location attribute of medical institutions， number of previous visits to this hospital， payment method of medical expenses， previous hospitalization history in this hospital， frequency of outpatient visits within the past 12 months， self-rated disease severity， familiarity with the outpatient procedures， implementation of the follow-up service provided by the hospital， satisfaction with follow-up services， the grade of the hospital visited， geographical region of the hospital visited， and the department visited had an impact on the humanistic care experience during outpatient visits （P<0.05）. Multivariate analysis demonstrated that educational level （β=0.609， P=0.011）， self-rated disease severity （β=-0.646， P=0.047）， familiarity with outpatient procedures （β=4.784， P<0.001）， satisfaction with follow-up services （β=6.365， P<0.001）， and the grade of the hospital visited （β=-5.487， P<0.001） affected the humanistic care experience in outpatient medical treatment， explaining 24.4% of the total variation. ConclusionHumanistic care experience in TCM outpatient clinics is influenced by multiple factors. It is recommended to optimize the medical treatment process， strengthen doctor-patient communication training， and establish a precise follow-up mechanism， with a focus on improving care perceptions among patients with lower education levels and those attending primary-level hospitals， to refine the TCM-characterized service system.

The high incidence of bleeding after peripherally inserted central catheter (PICC) catheterization increases the risk of puncture site infection and unplanned extubation. Hemostatic dressings should be used in the early stages of catheterization to reduce blood infiltration. However, new hemostatic dressings have various types and advantages, which makes them difficult to choose dressings for medical staff. This paper introduces the types and hemostatic characteristics of novel functional hemostatic dressings, reviews the hemostatic mechanism and hemostatic effect of chitosan, cyanoacrylate gum, alginate, gelatin sponge and oxycellulose dressings in PICC puncture respectively, and prospects the development of new functional hemostatic dressings. It is expected that future hemostatic dressings will move towards multifunctionality and compositeness.

Obesity is a significant risk factor for cancer and is associated with breast cancer metastasis. Nevertheless, the mechanism by which alterations in systemic metabolism affect tumor microenvironment (TME) and consequently influence tumor metastasis remains inadequately understood. Herein, we found that perturbations in circulating metabolites induced by obesity promote metastasis-like phenotypes in breast cancer. Oleoylcarnitine (OLCarn) concentrations were elevated in the serum of obese mice and humans. Administration of exogenous OLCarn induces metastasis-like characteristics in breast cancer cells. Mechanistically, OLCarn directly interacts with the Arg176 site of adenylate cyclase 10 (ADCY10), leading to the activation of ADCY10 and enhancement of cAMP production. Mutations at Arg176 prevent OLCarn from binding to ADCY10, disrupting the ADCY10-mediated activation of cyclic adenosine monophosphate (cAMP) signaling pathway. This activation promotes transcription factor 4 (TCF4)-dependent kinesin family member C1 (KIFC1) transcription, thereby driving breast cancer metastasis. Conversely, the neutralization of both ADCY10 and KIFC1 through knockdown or pharmacological inhibition abrogates the oncogenic effects mediated by OLCarn. Hence, obesity-induced systemic environmental changes lead to the aberrant accumulation of OLCarn within the TME, making it a potential therapeutic target and biomarker for breast cancer.

Although cisplatin is a widely used chemotherapeutic agent, it is severely toxic and causes irreversible hearing loss, restricting its application in clinical settings. This study aimed to determine the molecular mechanism underlying cisplatin-induced ototoxicity. Here, we established in vitro and in vivo ototoxicity models of cisplatin-induced hair cell loss, and our results showed that reducing STING levels decreased inflammatory factor expression and hair cell death. In addition, we found that cisplatin-induced mitochondrial dysfunction was accompanied by cytosolic DNA, which may act as a critical linker between the cyclic GMP-AMP synthesis-stimulator of interferon genes (cGAS-STING) pathway and the pathogenesis of cisplatin-induced hearing loss. H-151, a specific inhibitor of STING, reduced hair cell damage and ameliorated the hearing loss caused by cisplatin in vivo. This study underscores the role of cGAS-STING in cisplatin ototoxicity and presents H-151 as a promising therapeutic for hearing loss.

During the hyperacute phase of intracerebral hemorrhage (ICH), the mass effect and blood components mechanically lead to brain damage and neurotoxicity. Our findings revealed that the mass effect and transferrin precipitate neuronal oxidative stress and iron uptake, culminating in ferroptosis in neurons. M6A (N6-methyladenosine) modification, the most prevalent mRNA modification, plays a critical role in various cell death pathways. The Fto (fat mass and obesity-associated protein) demethylase has been implicated in numerous signaling pathways of neurological diseases by modulating m6A mRNA levels. Regulation of Fto protein levels in neurons effectively mitigated mass effect-induced neuronal ferroptosis. Applying nanopore direct RNA sequencing, we identified voltage-dependent anion channel 3 (Vdac3) as a potential target associated with ferroptosis. Fto influenced neuronal ferroptosis by regulating the m6A methylation of Vdac3 mRNA. These findings elucidate the intricate interplay between Fto, Vdac3, m6A methylation, and ferroptosis in neurons during the hyperacute phase post-ICH and suggest novel therapeutic strategies for ICH.

Ovarian cancer poses a significant threat to women's health, necessitating effective therapeutic strategies. Emd-D, an emodin derivative, demonstrates enhanced pharmaceutical properties and bioavailability. In this study, Cell Counting Kit 8 (CCK8) assays and Ki-67 staining revealed dose-dependent inhibition of cell proliferation by Emd-D. Migration and invasion experiments confirmed its inhibitory effects on OVHM cells, while flow cytometry analysis demonstrated Emd-D-induced apoptosis. Mechanistic investigations elucidated that Emd-D functions as an inhibitor by directly binding to the glycolysis-related enzyme PFKFB4. This was corroborated by alterations in intracellular lactate and pyruvate levels, as well as glucose transporter 1 (GLUT1) and hexokinase 2 (HK2) expression. PFKFB4 overexpression experiments further supported the dependence of Emd-D on PFKFB4-mediated glycolysis and SRC3/mTORC1 pathway-associated apoptosis. In vivo experiments exhibited reduced xenograft tumor sizes upon Emd-D treatment, accompanied by suppressed glycolysis and increased expression of Bax/Bcl-2 apoptotic proteins within the tumors. In conclusion, our findings demonstrate Emd-D's potential as an anti-ovarian cancer agent through inhibition of the PFKFB4-dependent glycolysis pathway and induction of apoptosis. These results provide a foundation for further exploration of Emd-D as a promising drug candidate for ovarian cancer treatment.

ObjectiveTo investigate the protective effect of total lignans of Arctii Fructus on the retinal tissue in the rat model of type 2 diabetes mellitus. MethodWistar rats were randomized into normal， model， solvent， Shuangdan Mingmu Capsules （618 mg·kg^-1）， and low-， medium-， and high-dose （100， 200， 400 mg·kg^-1， respectively） total lignans of Arctii Fructus groups， with 16 rats in each group. The rat model was established by streptozotocin （STZ） combined with a high-fat diet and administrated with corresponding drugs by gavage once a day for 14 weeks. At the 14^th week， blood was sampled for the collection of serum from the abdominal aorta after anesthesia， and bilateral eyeballs were collected and frozen. Hematoxylin-eosin （HE） staining was used to observe the histopathological changes of the retinal tissue in rats. The pathological changes of retinal vascular network in rats were observed by retinal vascular tissue digestion and mounting The levels of vascular endothelial growth factor （VEGF）， tumor necrosis factor-α （TNF-α）， and intercellular adhesion molecule-1 （ICAM-1） in the serum were determined by the ELISA kit. ResultCompared with the normal group， the solvent group showed pathological changes in the retinal tissue， reduced retinal ganglion cells （P<0.01）， and retinal thinning （P<0.01）， decreased E/P value in retinal blood vessels （P<0.01）， and elevated serum levels of VEGF， TNF-α， and ICAM-1 （P<0.01）. Compared with the model group， the total lignans of Arctii Fructus increased the retinal ganglion cells （P<0.01）， thickened the retina （P<0.01）， and lowered the serum levels of VEGF， TNF-α， and ICAM-1 （P<0.05， P<0.01）. ConclusionTotal lignans of Arctii Fructus may lower the VEGF， TNF-α， and ICAM-1 levels to protect the retina.

Objective:To evaluate the role of reactive oxygen species (ROS) in attenuation of hypoxia-reoxygenation (H/R) injury in rat cardiomyocytes by pinacidil postconditioning and the relationship with nuclear factor erythrid 2-related factor 2 (Nrf2)-antioxidant response element (ARE) signaling pathway.Methods:Adult rat cardiomyocytes were isolated and cultured and then divided into 4 groups ( n=20 each) by a random number table method: control group (group C), H/R group, pinacidil postconditioning group (group P) and reactive oxygen scavenger N-(2-mercaptopropionyl)-glycine(MPG)+ pinacidil postconditioning group (group MPG+ P). Group C was continuously exposed to 95%O 2+ 5%CO 2 in an incubator at 37 ℃ for 105 min. The cells were exposed to 5%CO 2+ 1%O 2+ 94%N 2 in an incubator at 37 ℃ for 45 min followed by reoxygenation for 60 min to prepare H/R injury model. The cells were exposed to hypoxia for 45 min and then treated with pinacidil 50 μmol/L for 5 min followed by reoxygenation for 60 min in group P. The cells were exposed to hypoxia for 45 min, treated with MPG 2 mmol/L for 10 min, and then treated with pinacidil for 5 min followed by reoxygenation for 60 min in group MPG+ P. The content of Ca 2+ and activity of Nrf2 in cardiomyocytes were measured at the end of reoxygenation. The ultrastructure of cardiomyocytes was observed, and mitochondrial ultrastructure was evaluated using mitochondrial Flameng score. The expression of Nrf2, superoxide dismutase (SOD1), quinone oxidoreductase 1 (NQO1), and heme oxygenase 1 (HO-1) protein and mRNA was detected using Western blot and real-time polymerase chain reaction. Results:Compared with group C, the Ca 2+ content, Nrf2 activity and mitochondrial Flameng score were significantly increased, the expression of Nrf2, SOD1, NQO1 and HO-1 protein and mRNA was down-regulated ( P<0.05), and the damage to the ultrastructure of cardiomyocytes was aggravated in group H/R. Compared with H/R group, the Ca 2+ content and mitochondrial Flameng score were significantly decreased, the Nrf2 activity was increased, the expression of Nrf2, SOD1, NQO1 and HO-1 protein and mRNA was up-regulated ( P<0.05), and the damage to the ultrastructure of cardiomyocytes was attenuated in P group. Compared with P group, the Ca 2+ content and mitochondrial Flameng score were significantly increased, the Nrf2 activity was decreased, the expression of Nrf2, SOD1, NQO1 and HO-1 protein and mRNA was down-regulated ( P<0.05), and the damage to the ultrastructure of cardiomyocytes was aggravated in MPG+ P group. Conclusions:ROS is involved in attenuation of H/R injury by pinacidil postconditioning, which is associated with activation of the Nrf2-ARE signaling pathway in rat cardiomyocytes.
